Communication module KM2 - version B.

Basic description:

The KM2 communication module is designed to send data from the MR4316AC NG, DMR4316AC or W4320 MPPS controllers, hereafter referred to as devices, to the Internet. The data set is sent from the device once per second, the averaged data is sent to the Internet once per minute. The data can be viewed within the local network in a web browser on a computer or mobile phone, or uploaded and stored on www.wordnet.cz and selected data can be viewed in graphs in a web browser on a computer or mobile phone from anywhere. Storing data on a TMEP or WORDNET server is a chargeable service (costing in the lower hundreds of crowns per year) provided by a third party. The communication module is powered directly from the device, so it only works when the device is powered. The communication module connects to the device via a 1:1 cable with RJ12 connectors, so it can be placed further away from the gulator in a location with a better wi-fi signal. The data is transmitted wirelessly to the router or modem over the wifi network. Operation is indicated by an LED.

The KM2 communication module can also be connected to some older versions of controllers and wattmeters. However, you will definitely need to update the firmware to the above versions and you will need to add some components to the board. Estimated price for modification is about 150 CZK. If you are interested in modification, please let us know what version of the board you have. The board version is written on the board itself (Vx). Depending on the version of the board, we will determine if the modification is possible or not.
